The projected demand for electric power will require a significant increase in coal combustion over the next thirty years. The manner in which this coal-fired power generation takes place will be severely constrained by social and political concerns. It is clear that all future designs for coal combustors must have high thermal efficiencies and minimum stress on the environment. The Department of Energy has begun a program to plan and design High Performance Power Generating Systems (HIPPS) that will achieve at least 47% overall thermal efficiency while controlling NOx, SOx and particulates to one-quarter of the NSPS. In addition, these performance goals are to be achieved at a 10% lower cost of electricity. A team of seven research organizations, headed by UTRC, has evaluated several indirect-fired combined cycle designs which isolate the coal combustion products from the gas turbine working fluid. The procedure is to use both radiative and convective air heaters to transfer the energy of combustion to the compressor air without contamination. Because of materials limitations it will be necessary to use a natural gas-fired topping cycle to attain the appropriate turbine inlet temperatures required for high efficiency. The design considerations for the air heaters, combustor and the ash management system will be presented along with preliminary information on the resultant commercial plant design.
